Hibernate boilerplate

[karq]

Hey,


is there a way to eliminate/simplify hibernate bolierplate code?

I have a class EventManager and all the functions in there consist of basically the same code

example:

function:1
public final List  byName(String name){
        Transaction transaction = null;
        Session session =   HibernateUtil.getSessionFactory().getCurrentSession();
        try{
            transaction = session.beginTransaction();
             //some code here
            transaction.commit();
        }catch(RuntimeException e){
            if(transaction != null && transaction.isActive()){
                try{
                    transaction.rollback();
                }catch(HibernateException e1){
                    e1.printStackTrace();
                }
            }
        }
        
    }

function:2
public final void save(){
        Transaction transaction = null;
        Session session =   HibernateUtil.getSessionFactory().getCurrentSession();
        try{
            transaction = session.beginTransaction();
             //some code here
            transaction.commit();
        }catch(RuntimeException e){
            if(transaction != null && transaction.isActive()){
                try{
                    transaction.rollback();
                }catch(HibernateException e1){
                    e1.printStackTrace();
                }
            }
        }
        
    }
function: 3
public final List<Employee> byDepartment(String department){
        Transaction transaction = null;
        Session session =   HibernateUtil.getSessionFactory().getCurrentSession();
        try{
            transaction = session.beginTransaction();
             //some code here
            transaction.commit();
        }catch(RuntimeException e){
            if(transaction != null && transaction.isActive()){
                try{
                    transaction.rollback();
                }catch(HibernateException e1){
                    e1.printStackTrace();
                }
            }
        }
        
    }
function: 4.
....
and so on

There's not much you can do with the session and transaction stuff, but you could stick the standardised rollbackTransaction() code as its own method.

I do hope you are not actually eating that RuntimeException...:)
